An Improved Method of Hough Transform Circle Detection Based on theMidpoint Circle-Producing Algorithm

To conduct vision detection to the circle’s geometric feature of the machine parts’ images, a new circle detection method is put forward by joining the midpoint circle-producing algorithm and Hough transform, which improves the floating calculating of the midpoint circle-producing algorithm and other. The detailed implementation steps are given and the detection results show that the new method is feasible. Finally, the experimental comparison indicates that the proposed method is effective.
